SPECIFICATION fOrming' part of Letters Patent No. 780,611, dated January24', 1905.

I Application filed April 25, 1904:. Serial No. 204,870.

To all whom it may concern:

Be it known that we, GEORGE MASTERMAN and FRED MASTERMAN, citizens ofthe United States, residing at Memphis, Shelby county, State ofTennessee, have'invented certain new and useful Improvements inCotton-Cleaners, of which the following is a specification.

Our invention relates to certain new and useful improvements incotton-cleaners, and has especial reference to a cleaner in which thehulls and dirt are separated from the cotton by the action of anair-blast blowing in the same direction in which the drum moves, but ata faster speed than that of the drum. We carry out these objects as willbe more fully hereinafter set forth in the drawings, specification, andclaims.

In the drawings, Figure 1 is a'sectional end elevation on the centerline. elevation looking toward the machine in the direction of thearrow.

Referring now to the drawings, in which the parts are indicated by thesame or like numerals in all the views, 1 is a cylindrical casing,preferably of sheet metal, provided with an inlet-flue 2, through whichthe cotton is blown into the machine.

3 is an air and dust outlet flue which is regulated by a sliding door 4and which permits discharge of a part of the air and dust.

5 is the boll-discharge flue, and 6 the cotton discharge or hopper. j

' The casingl has bearings 77 at its ends, which carry a shaft 8, onwhich is mounted a drum 9 somewhat smaller than the interior of thecasing 1. This drum, which extends the full length of the casing, isprovided on its periphery with a series of rows of books 10 and isdriven in the direction shown by the arrow by a pulley 11, mounted onthe shaft 8.

12 is a small drum or corrugated roller which is located beneath thedrum 9 just clear,

Fig. 2 is a front said flue, which shaft is rocked by an arm 19,

connected by a rod with a crank-arm 21 on the shaft 13 of the roll 12and being swung by said arm between the position shown and the dottedposition 17 The action of the device is as follows: (Jotton is blownwith a strong blast through the flue-2. The heaters 17 loosen or tear itup and spread it out in the flue, which widens as it approaches thecasing 1 to the full width of said casing and thoroughly distributes thecotton along the entire length of the drumv 9. The direction of rotationof the drum will be seen to be the same as that of the air; but thespeed is much slower. The cotton is therefore caught by the hooks 10vand retained on them, while the bolls,leaves,and dust are blown aroundthe periphery of the casing. When they reach the flue 3, the dust andpart of the blast pass out through the opening, and the balance of same,with the heavy dust and hulls, drops down and out throughv the flue 5.The

cotton is caught by the corrugated roller 12, I which is driven at ahigher peripheral speed than the drum 9 and is rolled through the spacebetween the drum and roller, forming thus an effective cut-ofl' toprevent the blast passing and carrying the bolls through with thecotton. When the cotton passes the roller 12, it drops of. its ownWeight through the opening 6, such of it as fails to fall otl' beingbrushed off by the brush 22.

Having fully described our invention, what we claim, and desire tosecure by Letters Patent in the United States, is

1. A cotton-cleaner, comprising a casing, a

drum having hooks thereon revolving in said casing, a cotton-inlet,beaters mounted at the entrance to said inlet, a dust and air outletoppositely disposed, a boll-outlet and a cottonoutlet arrangedsubstantially as described.

2. A cotton-cleaner comprising a casing, a drum having peripheral hooksthereon, mounted in said casing, an air and cotton inlet flue leading tosaid casing, fixed and swinging arms mounted at the entrance to saidflue, and means for reciprocating said swinging arms, of a dust and airoutlet leading from the opposite side said drum substantially as and forthe purof said casing, a boll-outlet, a cotton-outlet, poses set forth.and a roller coacting with said drum between In testimony whereof wehave signed our said boll and cotton outlet. names to this specificationin the presence of 5 3.
